- W3172051249 abstract "In view of the weakness of the existing STL data model's copyright information embedding technology, an information hiding algorithm based on DCT algorithm is proposed. Firstly, the STL data model is processed by PCA to eliminate the influence of model space transformation. Secondly, the embedded key information is selected and encrypted by Arnold transform. Finally, by using DCT transform, the STL model is generated by embedding copyright message into robust space, and the model error is evaluated. Simulation results show that, compared with the spatial domain protection methods such as histogram shift, the algorithm has stronger anti-attack ability under the normal display of the model." @default.
